Polokwane - The arrest of a relative of the farmer killed at his smallholding near Thabazimbi on Friday illustrates that not all farm attacks involve race, Sanco said on Sunday. "The fact that the arrested suspect is a relative [of] the murdered 54-year-old... highlights that some callous farm murders are not politically and or racially motivated but are crimes of passion involving family disputes," Sanco spokesperson Jabu Mahlangu said in a statement. The suspect allegedly attempted to commit suicide by shooting himself, however he survived.Police spokesperson Lieutenant-Colonel Moatshe Ngoepe previously said a manhunt was launched for those involved in the murder of farmer Bertie Cilliers, 54, who was found dead at the Spitskop smallholding on Friday. A tip-off was received that the suspect, understood to be Cilliers' son-in-law, was seen in the Rustenburg area.Officers pursued the man, who fled when police tried to pull him over."He drove off at a high speed and a chase ensued along the Sun City road. When he was cornered and pulled off the road, he allegedly shot himself in the head with the firearm believed to be the one used during the farm attack," Ngoepe said.He was taken to hospital and is being treated under police guard.Mahlangu said right-wing organisations "have opportunistically and for political expedience [chosen] to characterise farm murders not as a crime against which all South Africans should unite but as white genocide". "Unfortunately, some own goals have mostly contributed to a resurgence of racism that undermines peaceful co-existence within our communities, unity, reconciliation, nation building and social cohesion," he said. "Vigilance in farming communities as well as among role players involved in rural safety will eliminate the threat of opportunistic crime particularly during the festive season."
